What will be scraped

Prerequisites

Basic knowledge scraping with CSS selectors

CSS selectors declare which part of the markup a style applies to thus allowing to extract of data from matching tags and attributes.

If you haven't scraped with CSS selectors, there's a dedicated blog post of mine about how to use CSS selectors when web-scraping that covers what it is, pros and cons, and why they're matter from a web-scraping perspective and show the most common approaches of using CSS selectors when web scraping.

Reduce the chance of being blocked

There's a chance that a request might be blocked. Have a look at how to reduce the chance of being blocked while web-scraping, there are eleven methods to bypass blocks from most websites.

Install libraries:

pip install parsel playwright

Full Code

from parsel import Selector
from playwright.sync_api import sync_playwright
import json, re 


def scrape_researchgate_profile(profile: str):
    with sync_playwright() as p:

scrape_researchgate_profile(profile="Agnis-Stibe")

Code explanation

Import libraries:

from parsel import Selector
from playwright.sync_api import sync_playwright
import re, json, time

Code	Explanation
parsel	to parse HTML/XML documents. Supports XPath.
playwright	to render the page with a browser instance.
re	to match parts of the data with regular expression.
json	to convert Python dictionary to JSON string.

Define a function:

def scrape_researchgate_profile(profile: str):
    # ...

Code	Explanation
profile: str	to tell Python that profile should be an str.

Open a playwright with a context manager:

with sync_playwright() as p:
    # ...

Define the structure of the extracted data:

profile_data = {
    "basic_info": {},
    "about": {},
    "co_authors": [],
    "publications": [],
}

Lunch a browser instance, open and goto the page and pass response to HTML/XML parser:

browser = p.chromium.launch(headless=True, slow_mo=50)
page = browser.new_page(user_agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.64 Safari/537.36")
page.goto(f"https://www.researchgate.net/profile/{profile}")
selector = Selector(text=page.content())

Code	Explanation
p.chromium.launch()	to launch Chromium browser instance.
headless	to explicitly tell playwright to run in headless mode even though it's a default value.
slow_mo	to tell playwright to slow down execution.
browser.new_page()	to open new page. user_agent is used to act a real user makes a request from the browser. If not used, it will default to playwright value which is None. Check what's your user-agent.

Update basic_info dictionary key, create new keys, and assing extracted data:

profile_data["basic_info"]["name"] = selector.css(".nova-legacy-e-text.nova-legacy-e-text--size-xxl::text").get()
profile_data["basic_info"]["institution"] = selector.css(".nova-legacy-v-institution-item__stack-item a::text").get()
profile_data["basic_info"]["department"] = selector.css(".nova-legacy-e-list__item.nova-legacy-v-institution-item__meta-data-item:nth-child(1)").xpath("normalize-space()").get()
profile_data["basic_info"]["current_position"] = selector.css(".nova-legacy-e-list__item.nova-legacy-v-institution-item__info-section-list-item").xpath("normalize-space()").get()
profile_data["basic_info"]["lab"] = selector.css(".nova-legacy-o-stack__item .nova-legacy-e-link--theme-bare b::text").get()

Code	Explanation
profile_data["basic_info"]["name"]	to access earlier created basic_info key, and then create a new ["name"] key, and assign extracted data.
css()	to parse data from the passed CSS selector(s). Every CSS query traslates to XPath using csselect package under the hood.
::text	to extract textual data from the node.
get()	to get actual data from a matched node
xpath("normalize-space()")	to parse blank text node as well. By default, blank text node is be skipped by XPath.

Update about dictionary key, create new keys, and assing extracted data:

profile_data["about"]["number_of_publications"] = re.search(r"\d+", selector.css(".nova-legacy-c-card__body .nova-legacy-o-grid__column:nth-child(1)").xpath("normalize-space()").get()).group()
profile_data["about"]["reads"] = re.search(r"\d+", selector.css(".nova-legacy-c-card__body .nova-legacy-o-grid__column:nth-child(2)").xpath("normalize-space()").get()).group()
profile_data["about"]["citations"] = re.search(r"\d+", selector.css(".nova-legacy-c-card__body .nova-legacy-o-grid__column:nth-child(3)").xpath("normalize-space()").get()).group()
profile_data["about"]["introduction"] = selector.css(".nova-legacy-o-stack__item .Linkify").xpath("normalize-space()").get()
profile_data["about"]["skills"] = selector.css(".nova-legacy-l-flex__item .nova-legacy-e-badge ::text").getall()

Code	Explanation
profile_data["basic_info"]["name"]	to access earlier created basic_info key, and then create a new ["name"] key, and assign extracted data.
re.search(r"\d+", <returned_data_from_parsel>).group()	to extract digit data via re.search() regular expression \d+ from the returned string. group() is to extract substring that was matched by the regular expression.
css()	to parse data from the passed CSS selector(s). Every CSS query traslates to XPath using csselect package under the hood.
::text	to extract textual data from the node.
get()/getall()	to get actual data from a matched node, or to get a list of matched data from nodes.
xpath("normalize-space()")	to parse blank text node as well. By default, blank text node is be skipped by XPath.

Iterate over co-authors and extract individual co-author, and append to the temporary list:

for co_author in selector.css(".nova-legacy-c-card--spacing-xl .nova-legacy-c-card__body--spacing-inherit .nova-legacy-v-person-list-item"):
    profile_data["co_authors"].append({
        "name": co_author.css(".nova-legacy-v-person-list-item__align-content .nova-legacy-e-link::text").get(),
        "link": co_author.css(".nova-legacy-l-flex__item a::attr(href)").get(),
        "avatar": co_author.css(".nova-legacy-l-flex__item .lite-page-avatar img::attr(data-src)").get(),
        "current_institution": co_author.css(".nova-legacy-v-person-list-item__align-content li").xpath("normalize-space()").get()
    })

Code	Explanation
::attr(attribute)	to extract attribute data from the node.

Next is to iterate over all publications and extract individual publications, and append to a temporary list:

for publication in selector.css("#publications+ .nova-legacy-c-card--elevation-1-above .nova-legacy-o-stack__item"):
    profile_data["publications"].append({
        "title": publication.css(".nova-legacy-v-publication-item__title .nova-legacy-e-link--theme-bare::text").get(),
        "date_published": publication.css(".nova-legacy-v-publication-item__meta-data-item span::text").get(),
        "authors": publication.css(".nova-legacy-v-person-inline-item__fullname::text").getall(),
        "publication_type": publication.css(".nova-legacy-e-badge--theme-solid::text").get(),
        "description": publication.css(".nova-legacy-v-publication-item__description::text").get(),
        "publication_link": publication.css(".nova-legacy-c-button-group__item .nova-legacy-c-button::attr(href)").get(),
    })

Print extracted data, and close browser instance:

print(json.dumps(profile_data, indent=2, ensure_ascii=False))

browser.close()


# call function. "profiles" could be a list of authors.
# author name should be with a "-", otherwise ResearchGate doesn't recognize it.
